We have just released version 4.2.4 of our Syncplify.me Server! software. This version features the following improvements:

Fixed: occasional lingering of sockets in CLOSE_WAIT status when behind firewalls that act as proxies

Fixed: occasional huge delay upon accepting new connections when the number of VFSs is high

Warning: upgrading to this version from any version prior to 4.0.34 will invalidate your license, so please if you are a customer – before you upgrade – contact us to request a license reset.

Note: if after the update you notice any unexpected behavior in the web interface, just hit Ctrl-F5 in your browser; that will force the browser to reload the page as well as all back-end scripts and update the ones that may have been cached from previous versions of the software.

This setting cannot be configured in the web interface, the only way to set it is at Windows registry level. Restarting the Syncplify.me Server! system services is not necessary, as this setting is pulled from the registry every time a new incoming connection is served. Continue reading

If you run Syncplify.me Server! hosted on a VM in the cloud or at some co-location provider, you are probably aware that your ISP uses traffic shapers to optimize the transfer speed and to prevent malicious users from abusing network resources.

In particular, you may experience issues between the requested SSH socket buffer and the advertised buffer size on the network. If that happens, we got you covered! As of version 4.0, in fact, you can use a special Registry key to force Syncplify.me Server! to use a socket buffer size that matches the one advertised by your network. Continue reading
